Buderus Boiler Question

If you are using a multizone relay board, the circulator is controled by thermostat. Call for heat is satisfied, circulator shuts off. The R2109 post purge is designed for a constant circulation type of system. If I remember your system correctly - you do not need the post purge.
Thanks,

    hi I have a g115 28 with lt160 and r2109 is it better to turn the taco 007 off right when a call for heat is done or is it better to let them run 10 minutes

    what is the best and why? will burner run time be better
    on milder days?

    thanks
